0 all whom it may concern Be it known that I, ALLAN E. MCCABE, a citizen of the United States, and a resident of Richmond, in thecounty of I-Ienrico and State of Virginia, have invented an Improvement. in Water-Heaters for Oil-Stoves, of which the following is a specification.

1 My present invention relates generallyto oil stoves, and more particularlyv to water heating attachments therefor, my object being the provision of a simple improved water heating casing constructed in such manner asto obtain maximum and eflective results in its water heating operation, and capable of substitution for the usual burner casing removably disposed, as at present, upon the burners of stoves of this character.

The further objects of my invention, re- Siding for the most part inthe details of construction of the substitute casing, will be apparent from the following description, detailing such construction and the advantages thereof, in which reference is made to the accompanying drawings, forming part of this specification, wherein- Figure 1 is a front elevation of a conventional oil stove in connection with which my improvements are mounted.

Fig. 2 is a detail vertical section substantially onthe line 22 of Fig. 1.

Fig. 3 is a vertical longitudinal section through certain portions of my improvements. 7

Referring now to these figures, I have shown in Fig. 1, a conventional type of oil stove, generally indicated at 10, the usual burner casings 11 of which, seen at the right in Fig. 1, are, as well known, detachably mounted upon the respective burners 12, and of the upright tubular form shown.

In connection with stoves of this type my invention provides a water holding heating casing 13, shown at the left in Fig. 1, and in detail in Fig. 2, which may be inserted in position to rest-upon the respeetive burner 14 of the stove when the usual casing 11 is removed, the water casing. 13 having a lower or base piece 15 in the form of an inverted frustum of a cone for direct engagement with the burner l4 andprovided at its upper edge with an annular rim 16 crimped, as shown, around the contiguous flanged lower ends 17 of the inner and.

outer walls 18 and 19, the latter of which, as seen particularly in Fig. 2, is tubular and of the same diameter throughout.

The inner wall 18 tapers in its length and in an upward direction so as to form water chamber 20fofannular form between the'same and the outer wall 19, which gradually enlarges in cross sectional area toward the top of the casing, the particular shape of the inner wall being for the purpose of detardingor partially confining the products of combustion passingupwardly from the burner 14 seas to provide for effective heating of the water within the chamber 20,

the upper extremity of the innertapering wall 18 being crimped, as seen at 21, around the inner flanged edge of a top plate 22, the

extending vertically within the base 15 of the casing and the lower portion of the in nor wall 18.

The water casing 13 so formed, of which one may be applied to any one or more of the stove burners, is supplied from a water tank 25 having an upper opening 26, as best seen in Fig. 3, provided with a hinged perforated door 27, the perforations of which provide for the outlet of steam. The tank 25, as seen in the figure last-mentioned, may also have a water gage, and may be supplied with water through suitable connections with the ordinary house water supply system.

The tank 25 is connected to the water casing 13 by a single feed pi e 31 extending from the base of the tan r, as seen in Figs. 1 and 3, and connected at its opposite end by a threaded clampingring 32 to a threaded nipple 33 extending laterally from ing care of both the inflow of water to the water casing 13 and the outflow of hot water to the tank 25.

In-F-ig. -1, where the watercasing 18 of my invention is shown as applied to one only of the series of burners ofthe stove,

at one end of the series,-the' water tank is shown as supported by a bracket 34 to one tions, and the substitution of one or more of the watercasings 13 for'one or more of the usual tubularsingle wall casings 11; It is to be appreciated further, that by the provision of a water space formed between the double wallsof the water casing and by the tapering construction of the inner wall thercoflthe partially confined or retarded products of combustion from the Copies of this patent may be obtained for respective burners'are prevented from waste :ful dissipation and the heat of the ordinarily wasted products taken up by the water instead; I 1

The tank 25 may have a draw off cook 40, one of which is seen Fig.1, whereby hot water maybe withdrawn from the tank, as needed for use.

I claim:

A water heating burner casin for oil stoveshaving a lower base piece ac apted to rest on the lburnerof an oil stove" and provided with an upper rim forming an inwardly presented annular groove, inner and outeifi walls provided with lower adjacent edges having abutting fiangesprojectingout wardly intosaid grooveand clasped within the rim of the said base piece, theinner wall taperi'ngto form a water space between the same and" the outer wallfsaid space grad- V ual1yincreasing in width in an upward direction, and a top piece connecting the up:

per spaced ends of theinner and outer walls and 'closingthe upper; end of the" water space, fortlie rpose described? l ALLAN.E. MoCABE.
